The value of "more" in tuple returned by fetch_page() should always be a bool.

	more = results and (
	iterator._more_results_after_limit or iterator.probably_has_next()
	)

For consistency, the type of more should always be boolean (as suggested by the function's doc-string). However due to the current evaluation, it can sometimes be a list.

In the case where there are no results found, results will be an empty list and hence so will more.

i.e.

[] and False = [] # Not "False"

I noticed this, as I am serialising these values into a Protobuf which is type checking.
